MOLD.

Application iled February 7, 1919. Serial No. 275,565.

To all whom t may concern,

Be it known that T, FRANK R. HAHN, a citizen of the United States, residing at Decatur, in the county of Macon and State of Tllinois, have invented certain new and useful improvements in Molds, of which the following is a specification.

This invention relates to improvements in molds for molding or casting units made of cement, concrete or other plastic material.

The principal object of this invention is the provision of such a mold construction whereby a plurality of units may be molded or east at the same time and whereby various kinds of units, this variation referring` to size, shape, decoration and the like, may be formed or cast in the same mold.

VFurther objects of this invention include improvements in details of construction and arrangement, whereby a simple and effective mold is provided which may be readily set up and taken down and operated with facility in the production of a plurality of units or articles.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the construction, combination and ar 'angement of parts hereinafter described and then sought to be defined in the appended claims, reference being had to the accompanying drawings forming a part hereof and which show, merely for the purpose of illustrative disclosure, a preferred embodiment of my iniention, it being expressly understood, however, that various changes may be made in practice within the scope of the claims without digressing from my inventive idea.

ln. the drawing- Fig. l represents a top plan. view of a mold constructed according to my invention and set up, ready for use,

Fig. 2 is a vertical longitudinal cross section taken substantially on line 2-2 of Fig. l.

Fig. 3 is a vertical transverse cross section taken substantially on line 3-3 of Fig. l.

Fig. l is a perspective view illustrating` the various parts and the manner and method of assembling the same.

Figure 5 is a perspective view of one form of article or unit which may be made in this mold, it being merely for illustrative purposes only. n

Figure 6 is a perspective view of a slightly modified form of the transverse brace member.

Broadly described, this invention comprises a base to which are preferably secured one side and one end piece. This base inember is provided with flanges to support a plurality of floor boards or pallets and between which partitions or dividing members may be placed. It is to be understood that suitable decorative impression plates may be placed against the side or end of the mold or on the pallet or on the partition or dividing member, according to the decorative effect desired. The mold further includes the removable side member and end member with means for securing and locking the various parts together.

Referring to the drawing more in detail, the numeral l designates the base men'iber 75 of the mold. This is preferably rectangular in shape, though it is obvious that its shape may be varied according to particular working conditions. lVhile this base member may be formed of any material, it is prefer-red to form the .same of steel or similar thin or sheet metal, in the form of a channel, having the sides 2 and the inturned flanges 3 and 4f, 3 designating the lower flange, and l the upper flange. The upper flanges parg5 ticularly are of sufficient width to support the pallets, as hereinafter described. The members forming this base are suitably connected by means of the bolts or rods 5, which extend transversely thereacross and the bracing and spreading members (5 may also be utilized to assist .in holding the parts of the base in proper relation to each other. This bracing member 6 is preferably in the forni of a channel, having the upper and lower flanges 7 cut away at the end and remaining end extension S bent at right angles so as to fit against the inside surface of the side 2 of the channel member forming part of the base. The bolts 5 cooperate with these brae- 10o ing and spreading members so as to securely brace and hold the base in proper size and shape, which is essential in molding or casting the various articles or units for building construction. y

One side 9 and one end l0 are permanently secured in position on said base member l. l/Vhile this is preferable it is obvious that this side and this end may be made detachable. Tt is to be noted that T provide slots or 110 recesses ll at various intervals along the upper corner or edge of one side member and one end member of the base, these slots or recesses extending partly into the sides 2 et the channel member and partly into the top flange l1' of this channel member. The detachable side member 12 and detachable end member 13 are provided with depending lugs or extensions 14 and 15, 111 designating the lugs or extensions on the side member 12, and 15 designating the lugs or extensions on the end member 13. v These lugs Or extensions on the side and end members are adapted to slip thru said slots or recesses 11 in the side and end members of the base 1. Due to the size et these slots or recesses 11, the side and end members may be inserted at an angle and then moved upwardly until the dependinglugs or extensions 111 and 15 bear against the vertical sides ot the channel member of the base 1, whereby the side and end members are positively held in true vertical positions relative to said base member.

1t .is to be understood that prior to the mounting of the removable side member 12 and removable end member 13 that suitable floor boards er pallets 1G are placed in the mold, resting upon the inturned upper lianges /1 of the base and that these pallets are separated by suitable, partitions or dividing members 17, which may be decorated or not, depending upon the character of work being made.

1vVhen the-side member 12 is placed in position it is secured at one end to the stationary end member 10 by means of a hook or similarl securing means 18. The end member 13 is then placed in position and moved to its proper vertical position and the locking bail 19 is forced into position. This bail has the elongated part 20 for en gaging the end member 13, and the side parts 21 tor engaging the side members 9 and 12 and to rest in the clips or brackets 22, which side parts 21 have the laterally turned end portion 223 to prevent relative longitudinal movement between the bail and the clip or bracket 22. It is to be noted that the upper outer edge of the end mem-v ber 1 3 is beveled or rol'uided, as at 241i-, so as to permit said bail to be readily forced into locking position. It is also to be noted that the inside lower edge of the end member 13 is rounded or beveled, as at 25, so as to permit this member to be moved upwardly and have a sort of wedging or pressing action against the adjacent itloor board or pallet and consequently all of the other members to force and hold them in proper position.

In addition to the locking means previously described, it may be found advisable to provide additional means for'liorcing the sides into proper position. One form of such a means is illustrated in the drawing. It includes making the end member 13 in two parts 2G and 27. The lug members 15 are secured to the part 26. Pins 28 pass y bers 26 and 27.

thru said member 2G and are secured to member 2T and also pass thru the lug members 15 to form, a guide for said members 27, having springs 29 on the outside thereof to resist separation ot the two memr1`he manually operated cam members 30 are pivoted to said lug members 15 and pass thru a suitable slot in member 26 into engagement with member 27. It is obvious that when these cam members are moved tothe position shown particularly in Fig. 2, that the member 27 will be forced inwardly against the tension of springs 29, so as to force the floor boards or pallets 16 and partitions or dividing members 17 closely in association with each other so that the units or parts molded or cast therein will all be of proper size.

1t is to be understood that at'ter the mold is set up, as described, the various sections o thereof will be lilled with cement, concrete or other plastic material used and the top thereof struck ott. Depending upon. the llorm ot material used, and allowing a sufiicient time for the same to set, the mold may be taken down and the various articles removed iter drying on their separate and individual pallets. Due to the construction utilized the molds may be piled one upon the other without injury or damage to the contents; thereof.

1t is therefore to be seen that 1 have provided a very simple and elective mold tor the purpose ot casting or moldino multiple articles or units at the same time, and which molds may be readily adapted by the use of diliierent kinds of pallets or Hoor boards and different kinds ot dividing members or par titions together with various decorative members to `form various kinds oi units, decorated or undecorated, as desired. 1t is also to be noted particularly in the use ot' a square or rectangular base that the various parts oit this mold are selt squaring when set up, so that the units or articles will all be molded or cast properly without further attention on the part ol the operator.

'It is to be noted that in Fig. G l show a slight modiiication in the construction of the brace member G. ln this ligure oi' the drawing it will be seenthat the upper flange 7 of this brace member G is cut out at a plurality of places, as at 31, the cut out flaps 82 being bent downwardly and then laterally, as at 33, and secured to the inside of the' lower horizontal 'flange ot the member G. This structure is utilized in case it is desirable to mold or cast articles of less width than the width ot the mold as a. whole. 1n that case,4 the side members 12 having the proper depending-.lugs la are moved inwardly into the mold and positioned in the proper cut out recess or opening 31, and when straightened up, they will assume a proper vertical position, due to the iai-renee fact that the lugs la will bear against the vertical out out parts or flaps 82,
